IMPROVEMENT IN- ATTACHING LOCKS TO DRAWERS, &c.

Specification forming part of Letters Patent N 0. [80,65 l, dated August1, 1876 application filed December 29, 1875.

To all whom it may concern:

Be it known that I, WILLIAM J; SCHIL- LING, of East New York, in thecounty of Queens, State of New York, have invented certain new anduseful Improvements in Locks and Cases, of which the vfollowing is aspecification This invention relates to that class of locks which areusually inserted in furniture, doors, drawers, cases, and similarplaces, and which looks are usually embedded in a recess in the wood,and the top plate thereof flush with the wood surface, being securelyfastened therein by means of screws; or the lockcase may be providedwith extension flanges or wings on the sides thereof, which may be plainor serrated with fins or teeth, for fastening and holding it in theWood.

The invention consists in the provision of an auxiliary anchor, by meansof which the lock is immovably held in its seat, and cannot be movedtherefrom by any ordinary amount of power or exertion, the constructionand application of which will be fully pointed out and described.

In the drawings, which form an essential part of this specification,Figure 1 is a front view of a lock and case. Fig. 4 is a cross-sectiontaken on line 0000 in Fig. 3. Fig. 3 is a top or plan view. Figs. 2 and6 are detached views of the anchors; and Fig. 5 is a modification ofthat shown in Fig. 1.

Similar letters of reference will indicate corresponding parts.

The use of the ordinary lock for insertion in wood-work of anydescription, particularly in articles of furniture, in drawers, doors,cabinets, chests, and cases, calls for the cutting away, in most cases,of a portion of the wood to form a recess on the interior, into whichthe lock is inserted, and fastened therein by a series of screws.

The object of my invention is to produce a lock-casing which, combinedwith the new anchor-pin', shall possess the necessary elements requiredto hold it firmly and immovably in place when embedded in the wood,without the use of screws, or any other device, excepting theanchor-pin.

A represents the wood of the door, drawer, chest, or other article inwhich the lock is to be inserted. B is the back plate, to the top ofwhich is attached the face-plate G. D is the front plate, which isattached to the back plate,

and covers the working parts of the lock. The I ing (it may be round) inthe center of front plate D. In Fig. 5 it is the same, while at E it isrepresented in the sides of the front plate in the form of recesses. Fis an opening in the top plate 0, directly over the recess E in thefront plate; but it may be formed in each end in some cases. G is theanchor-pin. Its top has a screw-head with screw slot or nick to receivethe screw-driver. It is, immediately below the head, reduced in size, soas to fit into the opening F in the top plate, though its size may beunreduced, and the opening E formed to correspond. Its base hasprojecting from one side an angular spur. or foot, 0, two forms of whichare shown in Figs. 2 and 6. This anchor may be inserted inside of thefront plate D, as it will not interfere with the lock mechanism, or onthe outside, as shown in Fig. 1. If on the inside, when it is turned thespur or foot 0 will project through the open- .ing E; if on the outside,the spur may rest in the opening E until it is required to be turnedinto the wood, as in Fig. 4.

When it is desired to insert this look into the wood, it is simplynecessary to use 'a bit or auger to bore a hole of the size of thetransverse width of the lock. Several holes are then bored of the depthof the lock, each hole overlapping the other until a cavity is formed ofsufficient length to receive the lock. The lock is then inserted intothe cavity, if it is of the ordinary form of casing; but if providedwith extension-wings of plain form, as in Fig. 1, or with serrated wingsor fins, as in Fig. 6, the lock is then driven down into the cavity bymeans of a mallet or hammer, or other power 4 applied to the top plate.In this latter case the plain wings or the serrated fins displace thewood at the sides, forming for themselves achanuel or groove until thelock is set home into place, with its top plate flush with the surfaceof the wood. It will be understood that before inserting the lock theanchor G must be placed in its position, as prexiously described, andcarried down with the look. A screw-driver is then inserted into theslot in its head, and the spur or foot 0 turned until it is completelyembedded in the Wood, thus holding the lock immovably in its seat. Thiswill be found very useful in the case of locks for chests, caskets, andboxes where there is a lid or cover, and its use will prevent the lookfrom being pulled out of its seat by prying up the lid or cover. Thismethod of anchoring'locks may be used in all varieties of looks that arenow attached by screws, in addition to such screws, as well as with theform of lockcas-, ings herein described.

Having thus fully described my invention,

WILLIAM J. SOHILLING.
